"...I'm here to present to you - not lectures that are part of some curriculum; but in fact, I've combed the universe for my favorite subjects, and I'm going to spend twelve lectures bringing those favorite subjects to you." Renowned astrophysicist and television host
Neil deGrasse Tyson discusses the various aspects of our universe in twelve separate half-hour long lectures (MLYT).

"
Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space. " -- Douglas Adams

The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

One of the hardest things for people to understand about the universe is just
how big it is. There are three approaches typically used in describing its size. The first, the song, was pioneered by
Monty Python (NSFWish, wireframe of naked woman) and then done just as masterfully by
the Animaniacs. The second, the zoom method has been featured
twice before here on the blue. The third method is the
comparison method (skip to 1:30, unless you like looking at a image of the solar system with terrible distorted orbits), yielding some truly
beautiful videos (this one found via the fantastic
Bad Astronomy blog). These videos go, at most, as far as looking at the local cluster or the Virgo Supercluster. There are two videos that attempt to show the size of the entire universe,
one unsuccessfully (although with great music) and
one successfully. (Warning, all links except the first one, are to YT videos).

Exit Mundi's thoughts on the latest anticipated apocalypse: the
coming apocalypse in 10,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000 A.D.. (No kidding.)

Beyond the Reach of God. Thought experiments involving the God-universe and the Nature-universe, the Turing-complete Game of Life, and a
lot of insightful back-and-forth in the comment section, to boot. One of the most interesting and thought-provoking essays I've read on the Internet in a very long time, by Eliezer Yudkowsky on his blog,
Overcoming Bias (via).

An Interactive Space Simulator "Smash planets together, introduce rogue stars, and build new worlds from spinning discs of debris. Fire a moon into a planet or destroy everything you've created with a super massive black hole. You can simulate and interact with our solar system: the 8 planets,160+ moons, and hundereds of asteroids, the nearest 1000 stars to our Sun, and our local group of galaxies."

Cartography is a skill pretty much taken for granted now, but it
wasn't always
so. Accurate maps were once prized state secrets, laborious efforts that cost a fortune and took years (or even decades) to complete.
How things have changed. (Yours now,
$110) It took almost 500 years to map North America, but it's only taken one tenth of that to map just everything else. In the last 50 years, we've been able to create acurate atlases of
two planets and
one moon (with a
second in the works). Actually,
we've done a lot more than that. We're actually running out of things to map.
Maybe Not.

MMmmm, doughnut. (NYT link, reg. req'd) Lots of great philosophical answers to the old universe question, like our galaxy is in some giant's fingernail, and others. How about this one? Our universe is the shape of a doughnut!
